The Deluxe Memory Boy Pedal from Electro-Harmonix features an analog delay pedal with the ability to tap in the delay time. The Deluxe Memory Boy also includes two types of delay time modulation, an effects loop in the feedback path of the delay block, an input gain control, tap tempo divide, and optional expression pedal control over four parameters: Delay Time, Feedback, Modulation Depth and Modulation Rate.
This pedal includes six knobs. The Delay knob controls the amount of signal that is circulated from the output of the delay block to its input. The Feedback knob controls the amount of signal that is circulated from the output of the delay block to its input. The Depth knob sets the amount of triangle or square wave modulation that is applied to the delay time, and is also used to set the maximum amount of modulation for expression pedal control. The Rate knob sets the rate or speed of modulation, and sets the maximum rate of modulation for expression pedal control. The Gain knob sets the input gain for the pedal. The Blend knob is a wet/dry control allowing you to vary the mix between direct and delayed signals. The Deluxe Memory Boy also has Tap and Bypass footswitches, and Tap Divide and Exp. Mode buttons as well.
